Oracle Certifications are considered as one of the most valuable certifications in the digital world. It also offers certification courses in JAVA programming. There are two major courses related to JAVA programming; one is for the beginner level programmers, OCAJP while the other one is at the advanced level, OCPJP which is for professionals.

The syllabus of OCAJP contains all the basics of JAVA programming, and OCPJP is course covering the part after the basics for which the person must have a strong hold on the basics. Together these two Java certifications make a developer a professional JAVA programmer. These courses are of high value to both the programmers and to the companies and industries looking for programmers to work with.

If you are planning to appear in any of the two courses, there will be a million questions coming in your mind. We cannot answer all your queries, but we can surely provide you the answers to the most frequently asked questions. Hopefully, these top ten frequently asked questions will help you understand the syllabus, exam type, and preparation methods.

Here are the top ten FAQs for OCAJP and OCPJP Certification exams:

1. What is the eligibility criterion for appearing in OCAJP and OCPJP exam?
If you are worried that you are not eligible to appear in the OCAJP exam due to your qualifications or your lack of knowledge, good news for you is that there is no eligibility criterion for appearing in the OCAJP exam. Anyone who has an interest in JAVA programming can take the course and appear in the exam. While to appear in the OCPJP exam, it is necessary to pass the OCAJP exam. As you must know that OCPJP is a continuation of the OCAJP course which deals with the basics of JAVA. Without the proper understanding of the basics, it is impossible for one to appear in the advanced version, which is the OCPJP certification exam.

2. What are the key differences in OCAJP and OCPJP exams?
The key difference between OCAJP and OCPJP is the level of the course. OCAJP covers the basics of JAVA programming which are important to be understood before moving further in this field. While OCPJP exam is the second step after a programmer becomes an expert in the basic level, this is the course which makes a JAVA programmer a professional JAVA programmer. It can be said that OCPJP exam is tougher than the OCAJP exam. But if a programmer is good with the basics, it will become a tool for the preparation of OCPJP exam. It is necessary to pass the OCAJP exam to appear in the OCPJP exam.

3. What are the benefits of being JAVA SE8 certified?
As already discussed, Oracle certifications are well-known all over the industry and companies. After passing the basic level OCAJP exam and the professional level OCPJP exam, a programmer is capable of doing wonders in the world of programming. Due to this, the worth of a programmer is raised and so does the payroll. Being certified will give you an elevated status among other programmers. There are hundreds of jobs for JAVA developers all around the world, especially in the United States and India. Being JAVA SE8 certified officially makes you a better programmer than all others who do not have this certification and the probability of you getting better jobs is higher.

4. To become JAVA certified, is it necessary to appear in two exams?
Yes, it is necessary to appear in two exams to become a certified JAVA programmer. Only passing the OCAJP exam (1Z0-803) will not make you a certified JAVA programmer. In any case, you must appear in two exams to gain certification. However, after passing OCAJP exam, there are two options available for you. These two options are; one can either appear in the IZO-810 exam which is commonly known as Upgrade Java SE 7 to Java Se 8 OCP Programmer or one can appear in the OCPJP 8 (IZO-809) exam to become a certified professional JAVA programmer. One must understand that just appearing in one exam won’t make them become certified.

5. How to prepare for OCAJP and OCPJP exams?
Here are some tips that can help you prepare well for the exams:(i) Practice:
The most important key to the door to success is practice. Practice makes a man perfect. It is recommended that a person appearing in the OCAJP or OCPJP exam must write programs in the JAVA syntax for practice. This does not only contribute to making one a pro at writing programs but also helps them understand the code sense, read codes and get familiar with the JAVA syntax, which is essential for clearing the JAVA exams.

(ii) Study Guide:
It is suggested that a person appearing in the JAVA certification exams must take help from the study guide to pass the exams with a good score. The benefits of taking help from the study guide are that it covers all exam topics and the pattern of the exam is clearly mentioned in the guide.

6. Is it necessary to use an exam simulator for the preparation of JAVA exams?
Exam simulator is an essential tool for preparing for JAVA certification exams. However, it is not mandatory, and it is entirely your choice to use it or not. It is an extra tool for people who wish to achieve a high score in the exam instead of just passing it. This helps in time management by providing an actual examination scenario.

7. What kinds of questions are asked in the OCAJP and OCPJP exams?
The questions are a combination of multiple choice questions and fill in the blanks. The questions are divided into three sections. One section is based on the coding in which the output of the given code will be asked, the second section will comprise of questions that will cover the theory, and the third section is based on API questions. The study guide can be referred to understand the types of questions in a better way.

8. If one fails in the exam, is there a chance that the same candidate can retake the exam?
Yes, if a candidate fails in an OCPJP exam, there is an option of re-take. For re-appearing in the exam, the whole registration procedure must be carried out all over again. There is a waiting period of 14 days before which one cannot register to re-appear in the exam. Sometimes, a discount is offered to the candidates who are re-appearing in the exam, so do check if there is a discount available at the time you are registering again.

9. What is the registration process of OCAJP and OCPJP exams?
For registration, there are multiple options available, both online as well as offline. For online registration, one can navigate to the PEARSON VUE website. The exam voucher can be bought from Oracle and then one must register himself on the PEARSON VUE website. These Oracle certification vouchers can be bought from several training institutions. Another method is to pay at the Oracle Testing Center, if you have one in or near your locality.

These are the top ten questions that are most frequently asked by the people who wish to appear in the OCAJP or OCPJP exam. Hope this list of FAQs was helpful to you, all the basics about the exam details have been covered here. For more information, one can visit the website or head up to the Oracle Testing Center (OTC).

Clearing these exams help the programmers set up standards and their worth increases by tons. The Oracle Certified JAVA programmers are needed in many large-scale companies. Once certified, these programmers can do wonders with the JAVA language.

Good luck to all the people out there who are planning to begin the journey of becoming certified professional JAVA programmers.

Going for Java Certification is a dilemma for most of the freshers in the software industry. Not only freshers, but even those with an experience of 1-2 years also remain confused about it. They wonder if at all these Java certifications will help them boost their career or earn a good salary? Well, to be true, Yes, it will! Java certification definitely gives a lift to the career graph and thereby in the payouts you receive. Better job prospects, higher income, and better chances of promotion are some of the primary benefits of Java Certifications. However, OCAJP 8 and OCPJP 8 add much more value to your profile apart from enriching you with the above mentioned primary benefits.

There are newbies in the software industry who don’t even know the meaning of the terms OCAJP, OCPJP, SCJP, and OCP, etc. Let us first get some clarity about these terms and their full forms. Amateurs often get confused with SCJP, and OCJP. SCJP has been widely used since long years, and thus most people remember only this name. SCJP is the abbreviated form for “Sun Certified Java Programmer,” while OCJP is the abbreviated form for “Oracle Certified Java Programmer.” The term OCJP came into existence when Oracle acquired Sun Microsystems. There’s only a difference of their name; otherwise, both the certifications are same.

Similarly, freshers also get confused about OCAJP and OCPJP. OCAJP is the abbreviated form for “Oracle Certified Associate Java Programmer” while OCPJP is the abbreviated form for “Oracle Certified Professional Java Programmer.”

OCJP was divided into two parts: OCAJP and OCPJP. Any candidate cannot get OCPJP certification until he/she is OCAJP certified.

Java certifications are imperative for newcomers in the software industry. Since they have the java certification along with the regular degree, they enjoy an edge over the ones who aren’t certified.

Everyone may have his/her reasons to get Java certification, but here are the top reasons why you should go for OCAJP 8 and OCPJP 8 certifications.

Reasons to Go For OCAJP 8 and OCPJP 8 Certifications:

1. The chance to learn Java deeply and rejuvenate your skills:
Oracle Java certification exam questions are designed in such a way that you’d be able to learn subtle concepts speedily while preparing for the Java certifications. In just a short span of time, candidates can learn the basics as well as the details of necessary APIs. As OCAJP is made to learn Java for beginners, it includes the fundamentals of Java in it. While OCPJP is for advanced Java and includes higher levels concepts of Java such as exception handling, Generics and collections, Built-in functional interfaces, Concurrency, Localization, and JDBC. Therefore, when a fresher goes through all of these concepts while preparing for Java certification, he/she is bound to get a deeper understanding of them all.

It’s also crucial to go for only Java 8 certifications because it consists of new features and thus, you’ll have an advantage in the interviews if you learn it. Even if you’re a good programmer, you’ll need Java certifications. As an artist should never be satisfied with his/her art, a developer should never be satisfied with his/her programming skills. When you do the same job regularly, it will slow down your learning skills. Thus, preparing for Java certifications can also act as a rejuvenation of your skills. If you want to test your competency, you can try going for the certification.

2. Aids in Written Java Tests:
OCAJP8 and OCPJP8 build proficiency by giving access to the latest features in programming. As there is a cut-throat competition at the fresher level than the experienced position in the software industry, companies have started to include Java written tests in the hiring process. It becomes much easier to clear these written tests once you’ve passed the Oracle Java certification exam. If you’ve certified, some companies may even consider you directly for the interview process and exempt you from the written examination. However, just reading Java articles and questions won’t help; you’ll have to do Java certification for long term benefits. Whatever you learn through the certification will remain with you for a longer period.

3. Higher Pay Package:
It may not be 100% accurate, but there are records which prove that OCAJP8 and OCPJP8 certified professionals get higher pay package than a Java programmer with same skills but without any Java Certification. Employers certainly give an edge to Java certified professionals over the non-certified ones. Many companies even make it an eligibility criterion to have OCAJP8 and OCPJP8 certification for the hiring process. It happens because a lot of time and money is saved by assuming that the certified professional will certainly have greater basic knowledge of Java concepts. And yes, if the candidates perform well in Oracle Java exam and get high score such as 90+, then it certainly boosts the confidence of the candidate and helps him perform better in the interview process too.

4. Employers Reimburse for the Certification:
Many businesses, especially start-ups pay for the expenditure and cost of the Oracle Java exam to encourage their employees. They do it because they know that it will increase the knowledge and skills of their employees which will ultimately lead to better performance and result. It’s certainly a win-win situation for both the employees and the employers.

If your company is offering you such an opportunity, you must grab it. In fact, it is a great motivation for the newbie in the software industry. You must be aware that if your company is sponsoring the Oracle Java certification cost, then you must work at the same company for at least six months. There’s a high probability that the companies will deduct the expenditure and the Oracle Java certification cost from your salary if you leave the organization before six months or any other time specially mentioned by your company.

Go through your company’s policies thoroughly before going for company sponsored certifications. To get the maximum benefit of the Java OCAJP8 and OCPJP8 certification, go for Oracle Java exams as early as possible.

5. Recognition and Network Resources:
Another advantage of getting certified is that the Java certification gives attention to you whether you are in a team or looking to get hired. You’ll notice that your impression in your team is much better and it’s because you’re Java certified. Your colleagues develop a high regard for your knowledge of Java subtle concepts as they can sense greater Java skills in you.

Java certifications also offer you great opportunity to increase your networking circle and make good friends. You can even expand your network through exclusive Java communities, online classes, networking sites, online forums, and technical conferences. The network can be a tremendous resource whenever you’re looking for either support or even something else. This competent support network can be particularly useful to you as you progress in your career.

Java is a continuously changing programming language, and thus you’ll need to update yourself with the latest features coming in this field of programming. Java certification exams mostly include questions related to the most recent happenings, and thus you’ll be advancing yourself when you take up Oracle Java certification exam.

Although Java certifications need time and money, they also add great value to your resume and of course, in your upcoming career. The latest Java version available at present is Java 8, so it’s best to go for OCAJP 8 and OCPJP 8 only rather than previous versions of the Java. Latest knowledge of new concepts of Java certainly takes you much ahead than your counterparts, whether you are an employee in a company or a fresher looking to advance your career in the software industry.

When you perform better in your chosen field, then there’s no need to say that there’s greater probability of having a fulfilling career and a successful life soon. Whether it’s a written Java exam, face to face Java interview, or telephonic Java interview, you’re bound to get excellent outcome if you pass the Java certifications with high score.

Oracle Java Certification Exam was earlier called as SCJP (Sun Certified Java Professional) but after the takeover by Oracle, it’s known as Oracle Java Certification Exam. It is divided into two levels- OCAJP and OCPJP. OCAJP includes Java for beginners, and thus it’s easier than OCPJP whereas OCPJP includes Advanced Java and thus, is complex than OCAJP.
